JACOB B. MASKER, OF NEWARK, NEW JERSEY.

IMPROVEMENT IN HAT-BLOCKS.

Specification forming part of Letters Patent No. 39,299, dated July 21, 1863.

To all whom t may concern:

Be it known that I, J. H. MASKER, of the city of Newark, in the county ot' Essex and State of New Jersey, have invented certain Improvements in Hat-Blocks; and I do hereby declare the following to be a full and exact description thereof, reference being had to the drawings which accompany this specification, making part ot the same.

The nature of my invention consists in permanently securing the tongue which keeps the par ts ofthe block in their proper positions on the part to which it is fast in a manner which prevents its ever moving out of' place, at the same timekeeping the parts of the block from shift-ing under the ironing process on the hatbody.

In the drawings, Figure 1 is a block in two parts, showing the improved tongue in its position. Fig. 2 is e top view of a block when together. Figs. 3 and 4 show the old manner ot the tongue, and Fig. 5 an edge and dat view of u new'tongue.

The same letters refer to the same parts in each figure.

In the method in common use the tongue a is held by nails, as shown in Fig. 4, and the bottom end of the tongue is iliade beveling, to accommodate the manner of cutting the groove l Vb by rotary cutters, which do not leave the lower end of the groove square. The beveled ends are shown at c, Figs. 3 and 4.

Theimproved manner of securing the tongue by inserting it in -a dovetailed or square-edged groove, as the case maybe, is shown at d, Figs. l and 2. Instead ot' depending on nails and glue alone, which so often yield to the heat and hard pressure of the smoothing-irons, shift ing is rendered almost impossible by inserting the tongue c in a groove 011 each part of the block.

It is desirable to have the block, when put together, come at once to a perfect level on its top, that the iron muy not mark the hat in passing over the joint. By making the groove of exactly the same depth in each part of the block and having the lower end, g, Fig. 5, of both tongue and groove square, this object is fully attained.

WVhat I claim, and desire to secure, is A hat-block made in sections, said sections being united to each other by a Wedge or dovetail iorrned tongue and groove, the tongue being in line with the base of the block, the tongue and groove terminating before rea-ching the crown, substantially as shown and described.
